Learning Objectives Ch. 52 Due Meeting 1 Wk 8
1. Define ecology. Identify the two features of organisms studied by ecologists.
2. Describe the relationship between ecology and evolutionary biology.
3. Distinguish between abiotic and biotic components of the environment.
4. Distinguish among organismal ecology, population ecology, community ecology, ecosystem ecology, and landscape
ecology.
5. Clarify the difference between ecology and environmentalism.
6. Define biogeography.
7. Describe the questions that might be asked in a study addressing the limits of the geographic distribution of a particular
species.
8. Describe the problems caused by introduced species and illustrate with a specific example.
9. Explain how habitat selection may limit distribution of a species within its range of suitable habitats.
Due Meeting 2 wk 8
10. Describe, with examples, how biotic and abiotic factors may affect the distribution of organisms.
11. List the four abiotic factors that are the most important components of climate.
12. Distinguish between macroclimate and microclimate patterns.
13. Provide an example of a microclimate.
14. Explain, with examples, how a body of water and a mountain range might affect regional climatic conditions.
